SILO.

Specification of Letters Patent.

' Patented Feb. 17, 1914.

To all whom it may concern I Be it known that I, GEORGE P. Yor MANs, a citizen of the United. States, residing at Galesburg, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Silos, of which the following is a'specification. I

This invention relates to improvements in silos.

The main objects of this invention are, first, to provide in a structure having a continuous door opening and a plurality of doors, an improved hinge. Second, to provide in a structure having a continuous door opening and a plurality of doors, an improved hinge whereby the doors are supported so ,that they may be superimposed. Third, to provide an improved door hinge by means of which, the door is clamped in place and at the same time, one which may be readily released to open 'thedoor.

Further objects, and objects relating to structural details, will definitely appear from'the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and point-' ed out in the claims.

A structure which is a preferred embodimentof my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a. detail elevationof a structure embodying the features of my invention, one complete door only being shown, with portions of doors above and below to show their operative relation. Fig. II is a detail vertical section taken on a line corresponding to line 22 of Fig. I. Fig. III is a detail horizontal section taken on a line corresponding to line 38 of Fig. I. Fig. IV is a detail perspective view of the hinge member 10, the bracket member 13, and the clamping or securing member 19, disassembled. Fig. V is a detail vertical section taken on a line corresponding to line 5-5 of Fig. III. Fig. VI is a detail section taken on a line correspondin to line 66 of Fig. II, through one of t e pintle ears. Fig. VII is a detail vertical section taken on a line corresponding to line 7-7 of Fig. I, showing the arrangement of the hoops 7 in the wall.

trated. supported by the angle lron cross bars 4, 5 which are provided wlth lugs 5 struck in to In the drawing, similar reference'characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direct-ion of the little arrows at the ends of the section lines.

Referring to the drawing, the structure illustrated, is a circular silo having a continuous door opening, the door casing comprising the angle iron uprights 1. These casing uprights 1 are arranged with their an les facing inwardly to engage shoulders 2 formed on the wall tile 3, a special form of wall tile being used in the structure illus- The' door casin uprights 1 are engage the uprights as shown in Fig. III.

The tile in the structure illustrated, are hollow and provided with notches 6 intheir end and cross walls. See Figs. III and VII.

The hoops 7 are arranged in these notches and embedded in the joint cement 8. See Fig. VII. The hoops are arranged over the cross pieces 4, which are, in practice, spaced to come opposite the joints of the tile in which the hoops are arranged. The hoops are thus entirely inclosed within the wall except where they cross the door openings.

Thedoors 9 are adapted to be superimposed one upon the other so as to form a substantially continuous closure when the doors ai'e closed. At the same time each door when open, is supported independently of the others when the doors are open and any door may, if desired, be left open and those in both their closed and their open position.

My improved door'hinge or support, comprises the arm-like hinge member 10, which is curved rearwardly at its inner end, as at 11, to clear the door casing when the member is swung inwardly through the door opening, the pintle ears 12.being at the end of the rearwardly projecting portion of the hinge member. On the outer end of the hinge member 10, is a pivoted bracket 13, the bracket pivot 14 being vertically dis- .above the open door are eifectively supported posed. The bracket 13 rests on a suitable bearing surface 15 provided therefor-on the arm. The door is provided with, a centrally disposed attaching plate 16 having a vertical slot 17 therein for the attaching bolt 18 carried by the bracket 13. The door is supported on the bolt 18 to permit it to adjust itself to the door below and also in opening it may be lifted up to lift it over any ma tcrial that may be behind the door,that is, it may be lifted a distance corresponding to the length of the slot 17 in the plate 16. The hinge member projects beyond the attaching plate 16 or beyond the center of the door and the bracket pivotis placed at the end of the arm. The door attaching bolt 18 is located on the bracket sothat it lies between the bracket pivot and the hinge pintles when the door is closed. With the parts thus arranged, the bracket serves as an extension for the hinge member 10 when the door is open and the door swings well out of the door opening.

The securing member 19 is pivotally mounted on the bolt 18 and adapted, when in its horizontal position, to engage the door casing upright 1 opposite the upright on which the hinge member 10 is pivoted. The securing member 19 is provided with 2. casing engaging cam 20 at its outer end. It is also provided with an arm 21 at its inner end adapted to engage the keeper 2 on the hinge member 10. This keeper and the arm are provided with cam engaging surfaces so that. as the securing member is forced to its horizontal position, the outer end of the hinge member 10 is forced forwardly and the door clamped in position. The securing member is arranged on the bolt 18 to bear the rear side of the bracket member 13 and when extended engages the hinge member 10, as shown in Figs. I and II.

The clip 23 on the securing member 19 engages over a segmental flange 24 on the bracket 13 for retaining the bracket and the securing member together so that when the securing member is swung down its engagement with the keeper 22 is insured. The keeper 22 limits the downward movement of the securing arm 19, holding it in a substantially horizontal position so that it coacts with the hinge member 10 in forming a step, the hinges and the cross pieces 4 constituting a ladder.

The pintlcs 25'are carried by brackets 26. The pintlcs 25 are provided with lugs 27, and the pintle ears with notched pintle holes 28 adapted when brought into register with the lugs, to permit the ears being engagedor disengaged from the pintles.

The doors are preferably provided with gaskets 29, as illustrated. In closing the doors, the bottom door is first closed and the succeeding doors swung and clamped into position with one resting upon the other. My improved hinge p r tits this so that a continuous closure is provided, although the doors may vary somewhat in length or should one door be clamped slightly out of position, the others may be readily accommodated thereto. When the doors are open, they may be swung entirely clear of the door opening, and it is not necessary that the material in the silo should be below the level of the lower edge of the door as the door can be lifted up and swung around over the material as described, and as the material is taken from under the door, it drops down until it is supported on the pivot bolt 18.

I have illustrated and described my improvements in an embodiment which I find to be practical and satisfactory. I am aware, however, that considerable variations in structural details are possible, but as such variations will be suggested to those skilled in this art by the disclosures here made, I have not attempted to illustrate or describe the same herein.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
